Quizplus · Accepted Answer

In a between-participants study with four independent variables, the sources of variance include the main effects of each variable, all possible interactions between these variables, and the error term. This results in 1 (main effect for each variable) * 4 (number of variables) + 6 (two-way interactions) + 4 (three-way interactions) + 1 (four-way interaction) + 1 (error term) = 16 sources of variance.
